Aha, that would be the issue then.  I've been using machines with i810 and 
i815 graphics, some of them had AGP video cards but I removed them (having no 
need for them on servers).  I'll try disabling the i81x and use an AGP card 
and see if it helps.

Except for the Pentium-M in my laptop according to Matthew.
